One of my clients has some issues such as slow logon and accessing Exchange. When I check the status of the DNS using nslook, it shows Default Server:  UnKnown and it is use IPv6 IP as DNS as shown below. Should we setup IPv4 IP or IPv6 IP as primary DNS IP?

If using IPv6 as DNS IP is fine, how do yuo fix unknown default server?
